Personnaly, I really don't like the "chapter system". I have the "Alien Quadrilogy" DVDs and I must say that this system, on a non-high-quality DVD player, it creates interrupts during the viewing (due to the time for the lent to skip a scene, or searching a supplemental scene), and sometimes, the lent go crazy (when the movie has to be calibrated to the audio).
I've experienced that with the Alien box, and I hate that, it really get be "out of the movie", if you see what I mean, especially on the 1st Alien film, where you have choice between the new Director's Cut (in this version, some scenes are not complete, so the lent has to skip some parts of the movie) and the "regular" version (in this one, the let has to skip entire extra scenes)...
Hopefully, I still have the previous DVD box...

So, I really don't know about Star Wars DVDs made in the same way. If it creates the same "interrupts", I will not enjoy it...
